[Haskell-cafe] Re: Valid Haskell characters

[Deborah Goldsmith]

No, the general category is not enough. Please read both references.  
As you can tell from DerivedCoreProperties.txt, for example:

# Derived Property: Uppercase
#  Generated from: Lu + Other_Uppercase

So general category Lu is not the same thing as "Uppercase"
